Of course people who don't yet get any benefits from the airport construction aren't vocal about increased investment in its infrastructure, even though collectively they'll be the beneficiaries.
This is a classic example of concentrated benefits and diffuse costs, with the concentrated benefit being the NIMBYs who live near the airport and benefit from the status quo, and the greater diffuse cost being what society at large has to lose from it not being built out.
I'm not familiar with how airport noise regulations work in The Netherlands, but the situation you're describing with Schiphol doesn't sound unreasonable at all.
Unlike a club next door the amount of noise from an airport should be easily predicted based on available data, we know where the planes were at at any given time, and can construct very accurate models of what the noise at any given point on the ground will be.
Why would the council need to show up to do noise measurements only to find that yes, the noise is pretty much exactly the same as what your neighbor next door is experiencing?
If the noise is being systematically underestimated that's another matter, which the courts could presumably sort out, but that they're relying on estimations seems like good policy to me.
The decision on whether to allow an airport to expand is a careful balance of a lot of different concerns. An honest government or regulator weighs those concerns honestly, but because of the financial concerns surrounding a big airport, there's always an incentive to game the system.
The tourism and extra revenue for other people does not help the people who suffer from the daily noise. The slight drop in house value isn't the problem, but the fact that they may have to move at all.
If your house has to be torn down to make place for a new runway, you hopefully get paid well over the market value for your house. But if your house can stay, but is suddenly right next to a runway, you may wish they'd bought your house, but airports usually don't reimburse those people the same way.
There's a good reason why airports have noise regulations. Unfortunately, it turns out those rules can be far too flexible. Around Schiphol, it turns out the measured noise doesn't count. They calculate how much noise you get, and if your experience is different, tough luck.
